I'm helping out a relative who found this rifle in their parent's home. Unfortunately there are no real markings on it and the pictures are poor. The best I can make of it is from a search on Claude AI: "It his is almost certainly an Ottoman Tüfek or Arab/Levantine flintlock musket, likely 18th–early 19th century, probably with a later percussion conversion. These were produced across the Ottoman Empire from Turkey through the Levant, Egypt, and North Africa. The ramrod channel in the butt stock is the defining feature — that's a very specific construction method tied to that region."

Unsure
